Accurate automotive data is the foundation of reliable valuations, market analysis, and business intelligence. This data exists across hundreds of websites, portals, and documents – but accessing it at scale, keeping it current, and maintaining quality requires sophisticated infrastructure.
We built a comprehensive data acquisition system that continuously collects automotive market data from multiple countries. The system feeds our valuation engine, market analytics, and various data products used by dealers, insurers, and financial institutions.
The Challenge
Building a reliable large-scale data acquisition system presents significant technical hurdles:
- Diverse data sources – information scattered across classified sites, manufacturer portals, dealer websites, PDF documents, CSV exports, and image files
- Anti-bot protections – modern websites employ CAPTCHAs, rate limiting, IP blocking, and sophisticated bot detection
- Data variety – new car prices, used car listings, technical specifications, parts information, fuel consumption data, equipment details, and dozens of specialized attributes
- Scale requirements – processing high volumes of requests while maintaining reliability
- Data quality – raw scraped data contains inconsistencies, duplicates, and errors that must be cleaned
- Multi-market coverage – different countries have different data sources, formats, and languages
- Constant change – websites frequently update their structure, requiring ongoing maintenance
